Eigen is required

git clone https://gitlab.com/libeigen/eigen.git

we also need the rzeta package https://github.com/HISKP-LQCD/rzeta as extra dependency

git submodule update --init --recursive

create a build directory and compile

mkdir build
cp example_build_script/do_cmake.sh  build
cd build
bash do_cmake.sh
